Abstract: An improved H-tap compression connector is crimp-connected to a pair of electrical conductors by dies of a crimping tool. The connector includes a connector body having a generalry H-shaped configuration defining a pair of conductor nests opening in 'opposite directions from a transverse axis. The connector includes first and second pairs of spaced-apart crimpable sidewalls extending in opposite directions from the transverse axis. Each pair of sidewalls includes a first sidewall having an inwardly curved distal extent defining a die engagement location and a second sidewall having a die engagement location at the end thereof. The die engagement locations of each of the sidewalls of each pair are located substantially equidistant from the transverse axis. The die engagement location of the curved distal extent of the one sidewall is constructed to have a radius of curvature which is substantially identical to the radius of curvature of the die to prevent rotation of the connector within the dies during crimping.

Title: Identification of liquid crystal display panels
Inventor: DALTON SCOTT W
IPC: G09G3/20
Filed: 1995-01-19
Granted: 1998-12-29
Abstract: A method that identifies the type of LCD panel used in a portable computer system based on the frequency of the oscillator signal of the DC-to-AC inverter in the LCD panel.  In this method, only one signal is routed from the LCD panel to the base unit of the portable computer system for the purpose of panel identification.   The inverter  oscillating  signal  is  used  to  increment  a counter during power on operations.  A system counter, which is clocked by a system clock, is used to determine the  number  of  system  clocks  needed  for  the  panel identification counter to reach a predetermined count. That number is compared with the entries of a table, in which each entry corresponds to a type of LCD panel.  In this manner, the type of LCD panel can be identified based on the  frequency of the  inverter  signal.   A corresponding entry in a second table is accessed to obtain a table entry for the identified LCD panel to a full table of LCD panel parameters.  The table entry is stored in a predetermined location in the Video ROM. During the video power on portion of the BIOS, the video BIOS routines access the predetermined location in the Video ROM to obtain the parameters to properly initialize the video controller.

Title: Progressive execution technique for mobile computing devices
Inventor: HAAS ZYGMUNT
IPC: H04L12/28
Filed: 1995-08-10
Granted: 1999-11-23
Abstract: A process for efficiently distributing processing between a mobile computing device having limited resources and at least one remote computing device having substantially greater resources than the mobile computing device, comprises establishing wireless communication between the mobile computing device and the remote computing device in response to a user's invoking of an application at the mobile device. The mobile computing device executes, in parallel, a first version of an algorithm for performing a function associated with the user-invoked application to obtain a first result, and the remote computing device executes a second version of an algorithm for performing the same function associated with the user-invoked application to obtain a second result. The results that are available first (generally the locally generated results) are presented to the invoked application on the mobile device. The application is thereafter updated with the most reliable results, which are determined by comparing the remotely-generated result with those locally generated at the mobile computing device and evaluating any difference therebetween.

Title: Pneumatic trigger valve for spray gun
Inventor: WHEELER ROGER D
IPC: B05B7/04
Filed: 1996-11-25
Granted: 1999-09-28
Abstract: The invention is directed to an improved pneumatic valve for use in paint spray guns of the type having a pneumatic trigger operating mode. When actuated by a trigger, the valve vents a pressurized chamber in the spray gun, causing a piston to move to open air and fluid valves for initiate spraying. The pneumatic valve is in the form of a snap in module which is easily replaced without the need to remove thespray gun from the spray booth and without the need to replace a number of smallparts. A small return spring and the pressurized air urge a valve poppet to a closed position. When the trigger is operated, the poppet is unseated to vent the pressurized chamber in the spray gun. The flow of air through the valve during painting prevents dirt and paint overspray from accumulating on the valve.

Title: Synchronous polarization and phase modulation using a periodic waveform with complex harmonics for improved performance of optical transmission systems
Inventor: BERGANO NEAL S
IPC: G02F1/01
Filed: 1996-12-23
Granted: 2002-12-17
Abstract: A method and apparatus is provided that yields improved performance by modulating the optical phase and polarization of an optical signal with a periodic waveform having harmonic content that is more complex than that associated with a simple sinusoidal waveform.  A phase modulator receives an optical signal onto which data has been modulated at a predetermined frequency.  The phase modulator modulates the phase of the optical signal in a continuous manner with the periodic waveform with complex harmonics where the fundamental phase modulation frequency is equal to the same predetermined frequency at which the data is modulated onto the optical signal.  In another illustrative embodiment of the invention, a polarization modulator further processes the optical signal by modulating the state-of-polarization of the signal in a continuous fashion with the periodic waveform with complex harmonics where the fundamental polarization modulation frequency is equal to the same predetermined frequency at which the data is modulated onto the optical signal.  In addition to being continuously modulated, the polarization modulation is performed so that the average value of the state of polarization over each modulation cycle is substantially equal to zero.

Abstract: A cellular packet data arrangement includes an interface unit (NIU) (36) to a packet data network and link interface units (LIUs) (38, 40) each providing a channel (32) to a respective radio transceiver (18) for communicating data packets with mobile terminals (22) each having an individual identifier (TEI).  Each LIU stores the TEI, channel number, and protocol data for communications with each terminal handled by the LIU. In response to a first LIU receiving a communication from a terminal whose communications have been on a channel handled by a second LIU, this is identified from the terminal's TEI not being stored (46) in the first LIU and being stored (44) in the NIU in respect of the second LIU, and the protocol data for the terminal is transferred from the second to the first LIU. To avoid a possible error condition, the first LIU  can suppress a reply to the communication from the terminal until this is resent.
